tonight on "world news." race against time. mitt romney gets the word he's in a slide in battleground states. what does he do today to turn it around and why is he showing up with bill clinton? game over. was this the worst call ever? >> two of the worst calls at the end of a football game i can remember. >> players, fans up in arms. who are these replacement referees. find out what we learned today. real money. are you losing tens of thousand of dollars. is the bank telling you what your home is really worth? how to get that money back. >> that's a lot better. and, look, no hands? has "the jetson's" car finally arrived? an announcement today, we'll soon be sharing the road with cars that drive themselves. >> go ahead much.

good evening. tonight we begin with the clock ticking and a candidate looking for a big move. 42 days to go until "your voice, your vote." and the new polls are tough. for republican governor mitt romney they show him in a slide in two absolutely critical battleground states, ohio and florida. what is happening and how will he turn it around. david muir is with the romney campaign tonight in ohio. david. >> reporter: diane, good evening to you. as you know no republican has won the white house without ohio. in fact those polls a bit of a reality check for the romney campaign. as for the convention bounce president obama received it certainly was on mitt romney's mind today. before arriving in ohio, mitt romney on stage with a former president, speaking at a forum for bill clinton's global initiative. >> governor, i thank you for being here, the podium is yours. >> reporter: a warm welcome from

clinton -- and a wry response from romney. >> if there's one thing we've learned in this election season, by the way, is that a few words from bill clinton can do a man a lot of good. [ applause ] [ laughter ] all i have to do is wait a couple of days for that bounce. [ laughter ] >> reporter: in reality, romney can't afford to wait which is why he's in ohio tonight side by side with his running mate for the first time in more than a month. >> ohio! >> reporter: no longer are they making a case against the president's record, they are now making a case for themselves repeatedly using the word "choice". >> this is an eye election which is a clear choice for the american people. >> reporter: today, something from romney about the president we haven't heard before. romney has long argued the president raised taxes on americans in his first term. today he appeared to argue the president had not done so. >> his idea now, he's not one

new idea. i admit this. one thing de not do in his first four years which he said he was going to do in the next four years which is to raise taxes. >> reporter: tonight the campaign would not say he made a mistake. look at the electoral map. with the current abc news projections. if president obama wins ohio, the path for romney is challenging. for example, he would have to pick up virginia, wisconsin, iowa, florida, new hampshire. and still would not have the electoral vote es needs. he would have to add colorado to get there. tonight these new campaign numbers reflecting the rough week last week. that secret tape. the words about 47%. the obama team up in eight states with this tonight. >> mitt romney dismissed 47% of americans for not pulling their weight. he attacked millions of hard-working people making 25, 35, 45 -- >> reporter: now, on that issue of taxes, what the governor said here today, talking about those taxes, the president did not

raise income tax rates in his first term. he has proposed raising taxes on families earning $250,000 or more. diane, tonight this campaign looking for a game-change. as you know the all important debate a week from tomorrow. they acknowledged mr. romney was practicing over the weekend and has research sessions this week. >> a lot of pressure on that debate. thank you, david. what about the man who will face the governor in that debate, the president. he was making a case today but before a world audience of allies and adversaries at the united nation. he gave a passionate tribute to the u.s. ambassador killed in libya and called on the room to make a united stand against extremism machine here's jake tapper. >> reporter: the president made the focus of his united nations speech about a man who wasn't there. >> i would like to begin today by telling you about an american named chris stevens. >> reporter: with a tribute to a u.s. ambassador to libya, attacked and killed in the dead of night in benghazi two weeks ago today. he extommed the humanity and

hope stevens stood for. today, we must affirm that our future will be determined by people like chris stevens, and not by his killers. >> reporter: but, in many ways, the president's speech seemed targeted at his domestic audience -- accused by republicans of glibly down playing the unrest in the muslim world, the president demanded an end to the violence. >> there is no speech that justifies the mindless violence. there are no words that excuse the killing of innocents. >> reporter: and while only days ago, the white house was asking youtube to review whether that anti-muslim film violated the terms of use -- today the president offered a full throated defense of freedom of speech. >> like me, the majority of americans are christian, and yet we do not ban blasphemy against our most sacred beliefs. >> reporter: that was followed by a call to stop those who fan the flames against the west and its allies. t is time to marginalize those that hate the west or israel as central politics. >> reporter: a smaller part of

today's speech was iran's nuclear program, a continued source of frustration and tension. despite efforts of outreach and tough sanctions, that country more than doubled its production rate of enriched uranium since obama took office. >> the united states will do what we must to prevent iran from obtaining a nuclear weapon. >> reporter: last year's meeting president obama met separately with more than a dozen world leaders. this year he had no such meetings scheduled prompting criticism that he's more focused this year on campaigning than goff earning. hillary clinton met with 20 world leaders in his place. diane. thank you so much from the white house, jake tapper tonight. and now we move on to football, and the split second call that had everyone up in arms today. professional football referees are locked out in a contract battle with the nfl and their replacements have been called in some pretty amateur venues.

last night was not pretty. here's dan harris. >> reporter: there are eight seconds on the clock the seattle seahawks are losing to the green bay packers. and the seattle quarterback throws a hail mary. >> fought for by tate with jennings, simultaneous. who has it? who will they give it to? touchdown! >> reporter: look at what the two replacement referees do. one of them rules it a touchdown while the other signals something entirely different. >> to me, it looks like a jennings interception. >> reporter: moments later, though. >> after further review, the call on the field stands. touchdown. the game is over. >> reporter: that set off an instant firestorm. >> this is comical to me. really. mike, i tell you, that's two of the worst calls at the end of a football game i can remember. >> reporter: the announcers complain, so does the packers' coach. >> if enever seen anything like that in all my years in football. >> and so does the quarterback. >> it's awful.

that's all i'll say about it. online others post the nfl commissioner's phone number and launch expletive-filled rants. today, president obama, himself, weighed in, saying the call was "terrible." a rare point of agreement with republican vice presidential candidate paul ryan, himself a packers fan. >> give me a break. it is time to get the real refs. >> reporter: the real refs have been locked out since june, as part of a labor dispute. all season, the replacement refs the league brought in have been the source of enormous frustration. so, who are they? according to espn, the man who called last night's touchdown is a local executive for bank of america who only officiated high school and junior college football games. today, we have also learned that another replacement ref -- not involved in last night's game -- has been fired from something called the lingerie football league for incompetence. if there's any good to come out of this, aside for seattle fans, >> oh, my god it's amazing. it was the best seahawks game i've ever seen. >> reporter: it's that this uproar may help end the lookout.

tonight, the two sides are reportedly back at the table. dan harris, abc news, new york. now i want to bring in michael wilbon from our espn co-hosts of "pardon the interruption". michael, let me get you to say what you think. all you said so cards this is fraud, bogus and incompetent. what is the one word you want to use? pronounce the one word for this. >> one word. shameful. i don't know they can be embarrassed. somebody might tell the people they're not actually wearing clothes. they don't seem to care. the ratings are going up. the popularity of the league is not threatened. so i'm not sure they care as much as the people that were going crazy monday night. >> but the players' association says even further that it's endangering the players. >> there are issue of safety involved as well as competitive issues. if you got those two thing, you would really look to have a league which is not thinking about the integrity of its game the way it says it does.

>> where does this end? how much longer will this go on? >> i don't see it being a tipping point. i hope i'm being too cynical and this will wind up resolving itself. relatively soon. i can see this going on for weeks not days. >> michael wilbon weighing in. thanks so much, and hello to everybody at "pti." >> thank you, diane. now we move on to a startling report from the national transportation safety board about two close calls in the air at one of the busiest airports, chicago o'hare. we just learned about planes so close, pilots have said they are only alive because of luck and their own fast reflexes. here's abc's alex perez. >> reporter: a potentially deadly mid air collision. express jet flight 6075 was taking off from chicago's o'hare in may 2011 when panic suddenly filled the cockpit. sky west 6958 was coming in on,

quote, a collision course. the express jet pilot was able to react quigley. after nearly being killed, i keyed up the mike and yelled to the tower controller what the expletive was that. three months earlier, another close call at o'hare, same situation, same runway. as a result of close calls at o'hare, the faa has taken action. there's a new intersection warning and the controllers responsible for those two run waifrs now sit right next to each other to eliminate confusion. there were seven near serious collisions across the country in 2011 and in this case, the credit goes to the pilot. >> i took overt pilot action to avoid an error. we got lucky. that's clearly a cause for concern. >> reporter: the faa points out 99.99% of airline operations went off without a hitch. though pilots and passengers may

wonder if that's good enough. alex perez, abc news, chicago. and still ahead here on "world news," how this family added tens of thousands of dollars to the value of their home with just a few simple and smart moves. you can too. it's "real money," next. want to try to crack it? yeah, that's the way to do it! now we need a little bit more... a little bit more vanilla? this is great!

there are some positive signs the market is turning around but here is the latest number tonight on how much the bubble burst. the average american home lost more than $40,000 in value. right now, more than 2 million americans have their homes up for sale. how do you make sure the bank appraisal of your home gets you the most money? abc's sharyn alfonsi is on the "real money" beat tonight. >> reporter: jessica doerres' whole family lived in this new jersey community. then, the whole family decided to move. >> we all put our houses on the market at the same time, they already sold. they're gone. >> reporter: but jessica and her husband, carl, are stuck in jersey. they bought the house for $325,000 six years ago. today, they're asking $225,000. a $100,000 loss. >> $100,000 is -- it's real money. >> reporter: what's worse, the house was just appraised at $190,000 -- $35,000 less than what they're asking. that gap could be a huge problem if they ever do get an offer. >> when a bank gets a low

appraisal, they often won't do the loan at all because they feel as though it overvalued the house and they feel at risk. so, you can implore with the bank that they get a second look. but, the fact of the matter is, it's rarely turned around. >> reporter: but could we turn it around? we brought in one of the country's top appraisal experts for the inside scoop. she let us in on three ways appraisers are sizing up your home. first, the first sight. >> walking into this house we need a hatchet, right? >> yes. >> i didn't bring my machete. >> this is a no-no. >> reporter: appraisers can hack off thousand of dollars from your home's value for just having an unkempt yard. and signed, the first sight matters too. a clean, clutter-free house can appraise 10% higher than the exact same messy house. second tip, small subliminals. she said you don't have to redo the entire kitchen.

just add a new facet adds value. >> it makes it look jazzier. >> reporter: and finally out with the old and in with a new. down stairs alex said an old tv can make a whole room look dated. so we got started. moving out that busy oversized furniture. slip covering what is left and cutting down the hedges. there's a lot to do and the next appraiser is coming in just two days. i left them with a list. it is seven pages long. you have 48 hours. good luck. they spent $1600 on improvements, but would it pay off? the appraiser was here and we were about to find out. meet tom, an appraiser for 26 years. he said it's part art, part science. >> what kind of improvements have you made to your home in the recent past? >> a lot. >> reporter: remember that out of control office? now, all business. the cluttered kitchen, cleaned up.

and the old facet, updated. and the living room, now spare. the old set, replaced with state of the art. but could those little changes really pay off? remember, the last appraisal came in at $190,000. the new appraisal? >> oh, good. >> that's a lot better. >> reporter: $214,000. a $24,000 increase. and they were such good sports, they did everything on that seven-page to-do list. and it paid off. remember, we spent $1600. for every dollar they spent they got $15 back on that appraisal. so it's a good lesson. the first appraisal, not the final word. the important thing here, don't panic. >> and what about prospective buyers? >> the house is still for sale, but they have people coming over and importantly coming back for a second look.

>> good luck to them and thank you so much sharyn. and coming up. are we looking at a bacon emergency? fear of shortage coast to coast. is it time to stock up? we have the answer when we come back. is it time to stock up? we have the answer when we come back. the pitch! whoa! so why are you doing his? only your doctor can determine if your persistent heartburn is actually something more serious like acid reflux disease. over time, stomach acid can damage the lining of your esophagus. for many, prescription nexium not only provides 24-hour heartburn relief, but can also help heal acid-related erosions in the lining of your esophagus. talk to your doctor about the risk for osteoporosis-related bone fractures and low magnesium levels with long-term use of nexium. possible side effects include headache, diarrhea, and abdominal pain. other serious stomach conditions may still exist. let your doctor do his job. and you do yours. ask if nexium is right for you. if you can't afford your medication, astrazeneca may be able to help. wthe future of our medicare andr electiosocial security. for...
